I found it interesting. Thank you.Sorry. An embryo sheep is one that is like a test tube baby. Conceived and then the embryos are harvested from the donor and implanted in a less valuable ewe to grow to term, lamb out, and raise. It is a way to get more good lambs from excellent ewes without tying up the more valuable ewe to produce only 2 lambs at a time. Before this was common good rams could sire lots of lambs but a top quality ewe could only produce at most 20 to 30 lambs in her lifetime. With embryo and egg harvesting a valuable ewe can produce over 100 viable embryos and eggs. Semen from male animals in most species can be collected and frozen in a nitrogen filled tank for later use. Embryos and eggs can also be harvested from the donor female and frozen for later implanting into a host female.
This practice comes into play when you can't import live animals from a country. South African Dorpers are the best but cannot be imported to the US. Not only can the animals not be imported but neither can much of anything else be imported from South Africa to the US. The semen and frozen embryos can be imported to Australia and then imported from Australia to the US.
The embryo ram I keep talking about is one I bought from Wes Patton. Wes and Jane imported a number of Fullblood frozen embryos and semen straws from Australia that were direct genetics from South African Dorpers. They were Fullbloods. He implanted the embryos into some of his good maternal commercial ewes. This is one of them I was able to buy. At the time I had put down my favorite Lewis ram and needed another mature stud ram to bring to Texas. With the recent loss of Moyboy last month, I now have only 2 mature stud rams for my flock.
Another idiosyncrasy of Dorper/White Dorpers is their registration system. Since the Dorper/White Dorper breed is one of those "made" breeds, adding other breeds to it over the years has been allowed through a series of strict rules. However the Dorper/White Dorper Studbook has 3 books for each breed -
Fullblood - Animals tracing their direct ancestry only to animals bred and produced in South Africa. Purebred - Animals that were produced by adding other breeds into the Dorper/White Dorper genetics thrugh the improvement plan. Purebreds must have a 93% or higher Dorper blood. Most registered Purebreds in the US today are 100% since most have Fullbloods in their immediate ancestry.
Percentages - these are the recorded Dorper/White Dorper crosses that are working their way to Purebred status.
This ram is a Fullblood embryo transfer ram. His name is Patton. I name my rams after their breeders. I also have an unregistered Fullblood black head Dorper ram lamb that was fostered onto a ewe I bought from Wes. I will use that black head ram for commercials. His name is Rommel.
Probably more information than you ever wanted to know but once I get started my fingers seem to just start typing on their own . . . .![]()
